FIG. 4 is an enlarged view of the workpiece edge clamping device and the input belt conveyor unit shown in FIG. 1, and FIGS. 5 to 14 are in sequence The operation state diagram of the water jet cutting device shown in FIG. 1 is illustrated.

Fig. 2 shows an enlarged view of the shape and operation concept of each clamping member, and a plan view of the workpiece edge clamping device.

First, referring to FIG. 1, the basic structure according to an embodiment of the present invention will be described.

The input belt conveyor unit 110 and the output belt conveyor unit 120 are arranged on a base frame (not shown in the figure).

The input belt conveyor unit 110 is used to load a plate-shaped workpiece 10 thereon, and to reciprocate the workpiece in the X direction, and the output belt conveyor unit 120 also loads the workpiece 10 thereon, and moves the workpiece 10 thereon. The workpiece 10 is moved back and forth in the direction.

In this embodiment, although the workpiece 10 may be a glass plate, the material and shape of the workpiece 10 can be variously changed.

The input belt conveyor unit 110 and the output belt conveyor unit 120 each have a plurality of rollers surrounded by belts.

As described above, since the configuration of the input belt conveyor belt unit 110 and the output belt conveyor belt unit 120 using rollers and belts is a very conventional technology, detailed descriptions thereof will be omitted.

The output belt conveyor unit 120 is arranged on the rear side of the input belt conveyor unit 110, and has a processing interval 130 therebetween.

The processing interval 130 extends in the Y direction, and the Y direction is orthogonal to the X direction which is the conveying direction of the input belt conveyor unit 110.

The nozzle 140 is arranged above the processing interval 130.

The nozzle 140 is used to spray pressurized fluid to process the workpiece 10. The pressurized fluid can be water or water mixed with abrasives.

The nozzle 140 cuts the workpiece 10 while moving in the Y direction orthogonal to the X direction, that is, cuts the workpiece along the extending direction of the processing interval 130.

A nozzle driving unit (not shown in the figure) is provided to move the aforementioned nozzle 140.

The nozzle driving unit can drive the nozzle 140 to reciprocate in the Y direction. In addition, the nozzle driving unit may drive the nozzle 140 to reciprocate in the vertical direction.

Although the nozzle driving unit is generally provided in the base frame in a gantry type, in some cases, the nozzle driving unit may be realized by a robot or the like.

The concentrator 150 is provided below the nozzle 140, that is, below the processing interval 130.

The concentrator 150 is used to receive the pressurized fluid discharged from the nozzle 140, and is usually provided in the form of a groove. In some cases, the concentrator 150 may be implemented to reciprocate in the Y direction together with the nozzle 140.

The structures of the input belt conveyor unit 110, the output belt conveyor unit 120, the nozzle 140, the nozzle drive unit, and the concentrator 150 as described above can be applied in various ways.

The output belt conveyor unit 120 is composed of a plurality of rollers and an output belt 122 covering the rollers. The roller located on one side of the plurality of rollers is a driving roller 121 for moving the output belt 122, and the remaining rollers are guide rollers. That is, the output belt 122 moves along the drive roller 121 through the rotation of the drive roller 121, and the guide roller guides the movement of the output belt 122.

As described above, the output driving unit 160 is configured to operate the output belt conveyor unit 120.

In this embodiment, the output drive unit 160 includes: an output drive motor 161, which is provided on the base frame; a driven pulley 162, which is mounted to the drive roller 121 of the output belt conveyor unit 120; and a timing belt 163, It is used to transmit the rotational force of the output drive motor 161 to the driven pulley 162.

Therefore, when the output drive motor 161 rotates, the rotational force of the output drive motor is transmitted to the driven pulley 162 via the timing belt 163, so that the drive drum 121 and the driven pulley 162 mounted to the drive drum rotate together and are output The belt 122 reciprocates.

The above-mentioned output driving unit 160 is only used to drive the output belt conveyor unit 120, and therefore is provided separately from the input belt conveyor unit 110.

Therefore, the output belt conveyor unit 120 and the input belt conveyor unit 110 may operate independently of each other.

On the other hand, the input belt conveyor unit 110 is composed of a plurality of guide rollers and an input belt 112 surrounding them. That is, there is no separate driving roller in the input belt conveyor unit 110.

The workpiece edge clamping device 170 is provided on the input belt conveyor unit 110 to clamp the edge of only one workpiece.

The workpiece edge clamping device 170 includes a rectangular frame 171 and a plurality of clamping members.

As shown in FIGS. 2 and 4, the rectangular frame 171 has a workpiece input space 171a for the workpiece at its center.

The shape of the workpiece input space 171a is also rectangular in plan view.

As shown in the enlarged view of FIG. 4, the input tape 112 is connected to the outer edge of the rectangular frame 171. That is, the input belt 112 forms a closed curve surrounding a plurality of guide rollers, and both ends of the input belt 112 are connected to the outer edge of the rectangular frame 171.

That is, when the belt holder 113 is bolted to the outer edge of the rectangular frame 171, both ends of the input belt 112 are fixedly inserted between the belt holder 113 and the rectangular frame 171.

Through this structure, the input belt conveyor unit 110 can move synchronously with the workpiece edge clamping device 170.

In the rectangular frame 171, the part where the belt holder 113 is coupled (the right side in FIG. 4) is loaded on the input belt 112, and other parts (for example, the left side in FIG. 4) are separated from the input belt 112.

2, a plurality of clamping members provided on the inner edge of the rectangular frame 171 will be described.

A plurality of clamping members are provided on the inner edge of the rectangular frame 171 to clamp the edge of the workpiece 10 introduced into the workpiece input space 171a.

The clamping members used in this embodiment are a fixed clamping member 172, a vertically movable clamping member 173, and a horizontally movable clamping member 174.

The fixed clamping member 172 includes an L-shaped fixed clamping bracket 172 provided inside the rectangular frame 171. The fixed clamping bracket 172 only clamps the workpiece 10 by supporting the edge of the workpiece 10, and cannot move vertically or horizontally.

The vertically movable clamping member 173 has: a vertical driven cylinder 173a coupled with the rectangular frame 171; and an L-shaped clamping bracket 173b coupled with the vertical driven cylinder 173a so as to be able to follow the vertical driven cylinder 173a Operate and move vertically.

In this embodiment, two vertically movable clamping members 173 are arranged in the rectangular frame 171 adjacent to the output belt conveyor unit 120.

When the vertically movable clamping bracket 173 b moves downward through the vertical driven cylinder 173 a, the vertically movable clamping bracket 173 b supports the edge of the workpiece 10 to clamp the workpiece 10.

When the vertically movable clamping bracket 173b moves upward through the vertical driven cylinder 173a, when a discharge space 173c is formed between the vertically movable clamping bracket 173b and the output belt 122 (see FIG. 11), the discharge The space 173c can discharge the workpiece from the rectangular frame 171.

The horizontally movable clamping member 174 has: a horizontal driven cylinder 174a coupled to the rectangular frame 171; and an L-shaped clamping bracket 174b coupled to the horizontal driven cylinder 174a so as to be able to follow the horizontal driven cylinder 174a Operate and move horizontally.

Therefore, when the workpiece 10 is introduced into the workpiece input space 171a of the rectangular frame 171 in the state of FIG. 2, the L-shaped clamping bracket 174b of the horizontally movable clamping member 174 moves toward the workpiece 10, and the edge of the workpiece 10 is doubled. Two fixed clamping members 172, four horizontally movable clamping members 174 and two vertically movable clamping members 173 are clamped, as shown in FIG. 3.

According to the embodiment, the number and arrangement of the fixed clamping member 172, the horizontally movable clamping member 174, and the vertically movable clamping member 173 may be variously changed.

The clamping device driving unit 180 for driving the aforementioned workpiece edge clamping device 170 will now be described.

The clamping device driving unit 180 drives the workpiece edge clamping device 170 to reciprocate in the X direction.

The clamping device driving unit 180 includes: a screw 181 that extends in the X direction and is rotatably supported by the base frame; a screw drive motor 182 that drives the screw 181 to rotate; and a nut member 183 coupled with a ball screw ( The ball screw-coupled to the screw 181 is set on the rectangular frame 171.

That is, when the screw drive motor 182 rotates the screw 181, the rotational movement of the screw 181 is converted into the linear movement of the rectangular frame 171 through the nut member 183 in such a manner that a ball screw is coupled to the screw.

In addition, when the rectangular frame 171 reciprocally moves in the X direction through the operation of the screw drive motor 182, the input belt 112 of the input belt conveyor unit 110 correspondingly moves reciprocally in the X direction.

In this way, the input belt conveyor unit 110 and the workpiece edge clamping device 170 move synchronously.

In this way, since the workpiece 10 can be accurately reciprocated in the X direction through the operation of the screw drive motor 182, the processing accuracy of the waterjet cutting device can be significantly improved.

The operation of this embodiment will be described with reference to FIGS. 5 to 14.

Fig. 5 is a state before the workpiece 10 is introduced. FIG. 2 is a plan view of the workpiece edge clamping device 170.

FIG. 6 is a state in which the workpiece 10 is introduced after the state in FIG. 5.

The workpiece 10 is introduced into the workpiece input space 171a of the rectangular frame 171 through a robot or the like. Thus, the workpiece 10 is loaded on the input belt conveyor unit 110. Here, the workpiece 10 has not yet been clamped.

FIG. 7 is a state in which the workpiece 10 is clamped after the state in FIG. 6.

The workpiece 10 is clamped by the movement of the horizontal clamping bracket 174 b of the horizontal clamping member 174 of the workpiece edge clamping device 170. FIG. 3 is a plan view of the workpiece edge clamping device 170 operated accordingly.

FIG. 8 is a state in which the workpiece 10 is positioned above the machining interval 130 after the state in FIG. 7.

When the workpiece edge clamping device 170 and the input belt conveyor unit 110 move in the X direction through the operation of the clamping device drive unit 180, and the output belt conveyor unit 120 is driven by the output drive unit 160 and moves to the processing interval 130 In the upper position, the workpiece is in the state immediately before waterjet machining.

Fig. 9 is a state in which waterjet machining is performed after the state in Fig. 8.

The clamping device drive unit 180 drives the workpiece edge clamping device 170 and the input belt conveyor unit 110 to reciprocate in the X direction, and the output drive unit 160 drives the output belt conveyor unit 120 and the workpiece 10 loaded thereon Move back and forth in the X direction. At the same time, after the nozzle 140 moves downward, it then reciprocally moves in the Y direction through the operation of the nozzle drive unit to perform waterjet processing.

Thus, the work 10 is divided into a processed product 11 processed by water jet cutting and a waste material 12 excluding the processed product 11.

In addition, since the workpiece 10 can be accurately reciprocated in the X direction through the screw drive motor 182, the processing accuracy can be significantly improved.

When the waterjet processing is completed, the nozzle 140 is moved upward by the nozzle driving unit so as not to interfere with the transmission of the rectangular frame 171.

FIG. 10 is a state in which the workpiece 10 is transferred to the output belt conveyor unit 120 after the state in FIG. 9.

The clamping device drive unit 180 drives the workpiece edge clamping device 170 and the input belt conveyor unit 110 to move in the X direction, and the output drive unit 160 drives the output belt conveyor unit 120 to move in the X direction to position the workpiece 10 The state loaded on the output belt conveyor unit 120.

FIG. 11 illustrates a state where the clamping state of the workpiece 10 is released after the state of FIG. 10.

The vertically movable clamping bracket 173b moves upward through the vertical driven cylinder 173a, and under the operation of the horizontal driven cylinder 174a of the horizontally movable clamping member 174, the horizontally movable horizontal clamping bracket 174b moves away from the workpiece. Move in the direction to release the clamped state of the workpiece 10.

In addition, the discharge space 173c is formed between the vertically movable clamping bracket 173b and the output belt 122, and the workpiece 10 can be taken out from the rectangular frame 171 through the discharge space 173c.

FIG. 12 illustrates a state in which the workpiece 10 is removed from the workpiece edge clamping device 170 to the input belt 112 after the state in FIG. 11.

That is, the clamping device driving unit 180 drives the workpiece edge clamping device 170 and the input belt conveyor unit 110 to move in the X direction (right in FIG. 12), thereby moving the workpiece 10 out of the workpiece edge clamping device 170 . In this case, the workpiece 10 will not interfere with the movement of the workpiece edge clamping device 170 due to the discharge space 173c.

FIG. 13 illustrates the state in which the processed product 11 of the workpiece 10 is output after the state in FIG. 12.

In other words, the processed product 11 is output from the water jet cutting device through a robot or the like. Therefore, the waste 12 except for the processed product 11 of the workpiece 10 remains on the upper side of the output belt 122.

At the same time, through the vertical driven cylinder 173a of the vertically movable clamping member 173 of the workpiece edge clamping device 170, the vertically movable clamping bracket 173b moves down to a position to support another workpiece.

FIG. 14 illustrates a state in which the waste material 12 is disposed to the outside after the state in FIG. 12.

While the output belt conveyor unit 120 moves in the X direction following the driving operation of the output drive motor 160, the waste 12 is removed from the output belt 122.

That is, in this embodiment, the removal of the waste 12 and the output of the processed product 11 are performed in a completely different manner, and the removal of the waste 12 is performed through the output belt conveyor unit 120, so that it is easy to automate the entire workpiece cutting process.

On the other hand, a new workpiece 10 is put into the workpiece input space 171a of the rectangular frame 171 through a robot or the like. This is the same state as in FIG. 6.

Thereafter, the process of FIGS. 7 to 14 is repeated.
